AMP MODE OVERVIEW

The AMP MODE circuit is based on a MOSFET transistor which is a very popular type of transistor to use for boost circuits because it has many “amp like” characteristics when it clips etc. There can be downsides to this circuit though.

Several very popular MOSFET boost circuits on the market have a very noticeable crackle when their boost knobs are rotated. We fixed this issue in the AMP MODE so it is perfectly silent when the boost knob is rotated and delivers nothing but a crushingly loud and harmonically rich boost!

Use the AMP MODE as a preamp for your overall signal, a boost to push an overdrive pedal even further into saturation, or as a post overdrive boost to clarify and push your guitar forward in the mix! The AMP MODE features 9-18V operation, true bypass switching and a tiny footprint featuring top mounted jacks!

TONE TIP!

"One of the most powerful things about the AMP MODE is how well it stacks with other pedals as well as it self! For years I have run two MOSFET boosts on my pedalboard with a Klon in between them. I used one of the boosts as an always on boost, and added a second boost when I wanted an overdriven rhythm tone. Finally when I wanted a saturated lead tone I would kick on the Klon and the two boosts along with the Klon would give me a super articulate and saturated lead tone." - Brad Jackson 






BOOST CONTROL

The single boost control sets the overall boost for the AMP MODE. The AMP MODE is a true boost in that when the boost control is fully counter-clockwise, it doesn't boost your signal, it instead acts as a unity gain buffer that emboldens your guitars signal to prevent against tonal loss when drive long cables etc.

DC INPUT

The AMP MODE can safely run from 9V-18V DC (center negative). Running it at 18V will give increased headroom and dynamic response. Do NOT exceed 18V!


     






    BYPASS SWITCH

    The BYPASS SWITCH is a mechanical true bypass switch.

      Great sturdy shelf, install can be a bit challenging
      Style: 3 Tier with Tower Bar, Style: 3 Tier with Tower Bar
      The shelf is great and does exactly what I wanted it to do. I will note that the instructions indicate you’re supposed to use a 6 mm drillbit to install the anchors which comes out to about a 15/64 size. I would recommend a quarter inch drillbit because I was really struggling to get those anchors in there. Several folks also said that it’s easiest to install with two people, but you don’t need two people if you have some way to prop the piece up while you’re marking the hole placements to drill (and I would definitely recommend having a level on it the entire time you’re working to make sure that it’s correct). Lastly, it is easiest to put it together first, and then mark the drill holes, put the piece aside and drill and install the anchors, and then screw it in. I will also caution folks to not overtighten the pipe connections, because the pipes will end up in a wonky direction in the end. Overall I am extremely happy with this piece and certainly for the price!!

      Easy to put together. Super cute in any room
      Style: 3 Tier
      I fell in love with these when we were at our kids home and we installed them for them. The way my daughter-in-law decorated them, I loved it. I ordered 3 of them. I ordered a two tier for my office, because the 3 tier was too big, and i have the 3 tier in my bathroom. They look so dang cute and finishes up the wall in those areas. They are sturdy and strong. Super easy to put together. No tools required, except when you need to hang them. It will require two people to hang them. You can put them together in less than 5 minutes. Not super heavy but strong. strong to hold several things on them. I had no parts missing. Everything came packaged very nicely. Very functional. I would definitely recommend.

      Shelf
      Style: 2-tier Vintage Industrial
      I’m giving a 4 star due to installation. Screws were too small for the anchors. Shelf is very nice and looks great . Took little more time than what should have been an easy hang .
